Hi Outlook,
The explanation in DataTypes is correct, it is compliant to SQL standard.
The problem is that JsonRowDeserializationSchema only support RFC-3339.
On the other hand, CsvRowDeserializationSchema supports to parse
"2019-07-09 02:02:00.040".
So the question is shall we insist on the RFC-3339 "standard"? Shall we
loosen it for usability?
What do you think @Dawid Wysakowicz <dwysakow...@apache.org> ?
Best,
Jark
